Circumference of circle = pi*diameter = 13pi cm
Area is pi*d^2/4 = pi*13^2/4 = 42.25pi cm^2.
Answer:
There is a vertical change of 3 units down.
The first thing we must do is find the amount of land that will be used for the 120 lots.
We must remember that 10% of the land will not be used for the lots.
We have then:

Then, we must consider the following conversion of units:

Applying the conversion we have:

Then, the amount of square feet for each lot is given by:
Answer:
There will be 32670 square feet in each lot.
Recall the Laplace transform of a second-order derivative,

and the transform of cosine,

Here, both
, so taking the transform of both sides of

gives
